Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a sterile single top support device which can be folded and stored on the side of an operating table. Background Art

[0002] During some surgical operations, the patient lies supine on the operating table. Before the operation, the skin of the surgical site must be disinfected first, and then a sterile sheet with a hole is used to cover the patient. The hole is used to expose the surgical site. When covering the patient with a sterile sheet, it should be noted that the sterile sheet cannot completely cover the patient's mouth, nose and face. The usual practice is to use a supporting device to lift the sterile sheet located in the patient's head area upwards, so that the sterile sheet is separated from the patient's face by a sufficient distance, so as to prevent the sterile sheet from adversely affecting the patient's breathing and also avoid increasing the patient's fear.

[0003] The existing supporting device usually includes a bottom fixing block and an L-shaped supporting rod. The bottom fixing block is detachably connected to the side of the operating table, and the lower end of the vertical rod of the L-shaped supporting rod is usually fixed to the bottom fixing block by a locking member, and the horizontal rod of the L-shaped supporting rod is horizontally placed above the operating table to provide support for the sterile sheet. In order to facilitate patients to get on and off the operating table, nurses need to frequently disassemble and assemble the supporting device to the operating table in the operating room during the day. Not only is the operation inconvenient and takes up a certain amount of operating time, but the whole supporting device is heavy, and frequent lifting and lowering and transfer within a day also consumes a lot of physical strength.

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 6 As shown, the utility model provides a sterile single top support device that can be folded and stored on the side of an operating bed, which includes a fixed splint 1, a first rotating rod 2, a second rotating rod 3 and an oblique support rod 4. The first rotating rod is preferably a rod with a square or rectangular cross-section. The inner side surface of the fixed splint 1 is provided with a clamping mechanism for clamping and fixing with the side of the operating bed. The structure and clamping method of the clamping mechanism are well known to those skilled in the art and are not described in detail here. The outer side surface of the fixed splint 1 is provided with a rotating connection hole 5, a horizontal locking hole 6 and a vertical locking hole 7. The first rotating rod 2 is rotatably connected to the rotating connection hole 5 through a connector 8 at one end. Figure 2 and Figure 5As shown, the connecting head 8 is a shorter circular rod perpendicular to the first rotating rod, and the end of the circular rod away from the first rotating rod has a round cake block, which is embedded in the rotating connecting hole. The rotating connecting hole is a T-shaped slot with a small opening and a large interior. A locking pin 9 is provided on the outer side of the first rotating rod 2, and when the first rotating rod 2 is rotated to a horizontal or vertical state, the locking pin 9 can be respectively inserted into the horizontal locking hole 6 and the vertical locking hole 7. The other end of the first rotating rod 2 is rotatably connected to one end of the second rotating rod 3. A storage groove 10 is provided on the inner side of the first rotating rod 2. When the second rotating rod 3 is rotated to be parallel to the first rotating rod 2, it can be hidden in the storage groove 10. The hiding here should be understood in a broad sense, and it can be hidden in only a part or all of it can be hidden in the storage groove. One end of the oblique support rod 4 is rotatably connected to the front side of the first rotating rod 2. When the second rotating rod 3 is rotated to be perpendicular to the first rotating rod 2, the other end of the oblique support rod 4 can be connected to the second rotating rod 3 through a positioning member so that the first rotating rod 2 and the second rotating rod 3 remain perpendicular to each other.

[0027] It should be noted that, for ease of use, the locking pin is generally configured to be unable to completely detach from the first rotating rod. Specifically, it may be connected to the first rotating rod through a tension spring in the following embodiment, or it may be connected to the first rotating rod through a chain or a connecting rope to ensure that the locking pin is not likely to fall off, thereby avoiding the problem of the locking pin being easily lost during actual use. The number of oblique support rods may be as follows: Figure 1 Only one is shown, but two may also be provided, namely, symmetrically arranged at the front and rear sides of the first support rod.

[0028] In one embodiment of the utility model, the locking pin 9 includes a hand pull head 11 and a pin rod 12, the hand pull head 11 is fixed to one end of the pin rod 12, the outer side of the first rotating rod 2 is provided with a plurality of mounting grooves for inserting a tension spring 13, one end of the tension spring 13 is fixedly connected to the bottom of the mounting groove, and the other end is fixedly connected to the hand pull head 11. When there is no external force, the tension of the tension spring 13 keeps the pin rod 12 in a state of horizontally penetrating the first rotating rod 2.

[0029] It should be noted that an outward pulling force can be applied through the hand pull head 11, thereby overcoming the pulling force of the tension spring on the locking pin, so that the pin rod is disengaged from the vertical locking hole or the horizontal locking hole, thereby completing the unlocking.

[0030] In one embodiment of the utility model, the horizontal locking hole 6 and the vertical locking hole 7 are located on an arc guide groove 14 with the center point of the rotating connecting hole 5 as the center, and the end of the pin rod 12 away from the hand pull head 11 is slidably matched with the arc guide groove 14.

[0031] It should be noted that the arc guide groove has a guiding function, so that one end of the pin rod pulled out from the horizontal locking hole or the vertical locking hole can remain in contact with and slide in the arc guide groove. When the first rotating rod is rotated into place, the pin rod is automatically inserted into the horizontal locking hole or the vertical locking hole under the action of the tension spring to achieve automatic locking.

[0032] In one embodiment of the utility model, the positioning member is a locking bolt 15, and the locking bolt 15 is threadedly connected to the front side of the oblique support rod 4. The front side of the second rotating rod 3 is provided with a positioning hole 16. When the second rotating rod 3 is rotated to be vertical to the first rotating rod 2, the oblique support rod 4 can be rotated to a position where the locking bolt 15 is aligned with the positioning hole 16 and at this time, after tightening the locking bolt 15, the end of the locking bolt 15 is inserted into the positioning hole 16.

[0033] It is understandable that, in addition to using the locking bolt in the above embodiment as the positioning member, a locking pin may also be used instead, and there are multiple options for the specific locking method.

[0034] In one embodiment of the utility model, a limiting hole 17 is further provided on the front side of the first rotating rod 2. When the oblique support rod 4 is rotated to be parallel to the first rotating rod 2, the locking bolt 15 is aligned with the limiting hole 17 and the end of the locking bolt 15 is inserted into the limiting hole 17 after the locking bolt 15 is tightened.

[0035] It should be noted that the function of the limiting hole is to lock the oblique support rod when it is parallel to the first rotating rod, so as to avoid any rotation thereof when not in use, which would cause inconvenience to the patient and medical staff.

[0036] In one embodiment of the present invention, a telescopic rod section 18 is provided at one end of the second rotating rod 3 away from the rotation connection between the second rotating rod 3 and the first rotating rod 2. When the second rotating rod 3 is rotated to be hidden in the storage slot 10, the first rotating rod 2 can be rotated to a horizontal state and stored on one side of the operating table.

[0037] It should be noted that the telescopic rod section can be almost completely retracted into the rod section of the second rotating rod that cannot be retracted, and can only be conveniently rotated to be hidden in the storage slot when it is retracted to the limit state. In order to facilitate the second rotating rod to be pulled out of the storage slot and rotated to unfold, a spring or spring can be provided at the bottom of the storage slot. When the first rotating rod is rotated to a horizontal state, the second rotating rod is subjected to pressure from the bed side so that the elasticity or spring at the bottom of the slot is compressed. When the first rotating rod is rotated upward to be away from the bed side, the spring or spring causes the second rotating rod in the storage slot to be partially ejected, thereby facilitating the medical staff to further rotate the second rotating rod upward to a horizontal state.

[0038] In one embodiment of the utility model, when the first rotating rod 2 is rotated to a horizontal state, the oblique support rod 4 is located on the upper surface of the first rotating rod 2. That is, when in the folded storage state, the oblique support rod is located on the upper surface of the first rotating rod, so that it is convenient to screw the locking bolt into the limiting hole to realize the positioning of the oblique support rod. When the limiting hole is a through hole, the locking bolt can also produce a pressing and positioning effect on the second rotating rod in the storage groove.

[0039] The basic principle of the supporting device provided by the utility model is that when the supporting device needs to be used, the first rotating rod is first rotated to a vertical state and the vertical state is maintained by a locking pin inserted into the vertical locking hole, and the second rotating rod is rotated upward to a horizontal state, and then the second rotating rod is maintained in a vertical state with the second rotating rod by the oblique support rod and the positioning member (that is, the second rotating rod is suspended above the operating bed to provide support for the sterile sheet to prevent the sterile sheet from pressing the patient's face); after use, the locking of the oblique support rod and the second supporting rod by the positioning member is first released, and the second supporting rod can be rotated downward to be parallel to the first rotating rod and hidden in the storage groove, and then the locking pin is unlocked, so that the first rotating rod and the second rotating rod therein can be rotated downward to a horizontal state as a whole and locked by the locking pin inserted into the horizontal locking hole. At this time, the entire supporting device is folded and stored on one side of the operating bed. The supporting device does not need to be frequently disassembled and transferred. After being folded and stored on the bed side, it does not affect the patient getting on and off the operating bed. It can be quickly unfolded and locked when it is needed, which saves time and effort and is easy to use.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
